The present invention relates to a technique of changing print data and print setting between different print modules.
As software for controlling a print apparatus, there has been generally known a system that uses a printer driver installed in a host computer. There has also been known a technique that allows an operating system (hereinafter, referred to as OS) to provide a standard printing function (hereinafter, referred to as OS-standard printing function) with no need of a printer driver of a vender who provides a print apparatus (International Publication No. WO2013/116704). The OS uses a specific protocol to receive the state of the print apparatus whether the print apparatus supports the OS-standard printing function, and transmits print data generated based on the setting by a user to the print apparatus.
However, it is impossible to use the OS-standard printing function in a print apparatus that does not support the OS-standard printing function. For this reason, there has been used an application called a print conversion utility to use the OS-standard printing function in a print apparatus not supporting the OS-standard printing function. This application includes therein the vender's own print system (hereinafter, referred to as print module) that is different from a print system (print module) provided by the OS, and interconverts a protocol used for the OS-standard printing function and a protocol unique to the print apparatus.
In an environment of using the print conversion utility, it is impossible to execute proper processing if the printing functions between two different print modules do not match each other.
A method of controlling an information processing apparatus according to an aspect of the present invention is a method of controlling an information processing apparatus configured to convert data received from a first print module into data appropriate for a print apparatus not supporting the first print module, including the steps of: obtaining first print data and first print setting from the first print module as a first obtainment step; obtaining capability of the print apparatus from the print apparatus as a second obtainment step; changing the first print data and the first print setting according to a type of the first print data, the first print setting, and the capability of the print apparatus; and converting the changed first print data and first print setting into data appropriate for the print apparatus to output the data to the print apparatus.
Further features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
Hereinafter, embodiments of the present invention are described in detail. The following embodiments are examples for describing the present invention and are not intended to limit the present invention to merely the embodiments. Additionally, the present invention allows various modifications without departing from the gist. The same reference numerals are assigned to the same constituents, and the descriptions thereof are omitted.
The ROM 112 stores an initialization program, and the external storage device 114 stores a group of application programs, an operating system (OS), print data generation software, and other various kinds of data. The RAM 113 is used as a working memory or the like for execution of the various programs stored in the external storage device 114.
In this embodiment, the CPU 111 executes processing according to the procedure of the programs stored in the ROM 112 to execute the functions described below of the host computer 101 and the processing according to the flowcharts described below. A print apparatus 102 as a device is connected to the host computer 101 through the input-output interface 116. The configuration in this case includes the host computer 101 and the print apparatus 102 separated from each other; however, the host computer 101 and the print apparatus 102 may be formed as a single information processing apparatus. Here is described an example where the print apparatus is an ink jet printer that performs printing by ejecting ink onto a paper surface; however, the printing may be executed by another method (for example, by electrophotographic method). The host computer 101 may be a desktop personal computer, a smartphone, or a laptop personal computer. The display unit 119 may also be configured to operate as an input unit like a touch panel display. The host computer 101 and the print apparatus 102 may be connected to each other through a network, and a not-illustrated print server may be connected to the network.
An application 201 is software that creates contents to be printed. Examples of the application 201 may be a text creating application, a spreadsheet application, and so on. Once receiving a printing request from a user, the application 201 issues a printing instruction to an OS 210. Once receiving the printing instruction, the OS 210 entrusts the OS print module 202 to execute the processing of printing thereafter.
In this case, the OS print module 202 performs operations compliant with IPP Everywhere (registered trademark), which is known as a technique capable of performing printing with no need of a printer driver provided by a print apparatus vender. IPP Everywhere is not a module including a printer driver for a specific print apparatus 102 but is a standard print module that can be shared and used in multiple print apparatuses. The OS print module 202 cooperates with the application 201 and generates print data and print setting for performing printing in the print apparatus 102.
First, a case where the print apparatus 102 supports the OS-standard printing function is described. In response to an instruction from the OS print module 202, an OS-standard print control component 203 communicates with the print apparatus 102 through the input-output interface 116 by using an OS-standard print protocol. In this case, the OS-standard print control component 203 executes the print processing according to a specification of a standard print protocol called the Internet Print Protocol (IPP) as the OS-standard print protocol. Additionally, the OS-standard print control component 203 uses a standard protocol called the Bonjour as a discover protocol for the print apparatus 102.
Once receiving the printing instruction from the application 201, the OS print module 202 provides a print setting screen to the application 201. The print setting screen is displayed on the display unit 119. The print setting screen is displayed according to information returned from the OS-standard print control component 203 to the OS print module 202. The print setting screen includes a list of available print apparatuses 102 supporting the OS-standard printing function, for example. The print setting screen is configured to display a printing function that can be set and the set value thereof according to settable printing information that can be set for each print apparatus 102. The print setting screen displays the printing functions that can be set, such as setting of the number of copies, setting of layout printing, setting of collation printing, and setting of two-sided printing, and the set values thereof. The settable printing information is information that the OS-standard print control component 203 obtains from the print apparatus 102 and provides to the OS print module 202. The printing functions and the set values displayed on the print setting screen are provided by the OS print module 202 according to the settable printing information.
While displaying the print setting screen, the OS print module 202 searches for a print apparatus 102 supporting the OS-standard printing function by using a discovery protocol Bonjour through the OS-standard print control component 203. In this case, the OS-standard print control component 203 obtains a list of a print apparatus 102 notifying of Service Instance Name of “_ipp._tcp,_print” as DNS Service Discovery. The OS-standard print control component 203 returns the print apparatus 102 on the list to the OS print module 202 to notify that this print apparatus 102 supports the OS-standard printing function. In a case where there are multiple print apparatuses 102 supporting the OS-standard printing function, the OS-standard print control component 203 returns a list of the multiple print apparatuses 102 to the OS print module 202.
The OS print module 202 displays the print apparatus 102 supporting the OS-standard printing function returned from the OS-standard print control component 203 on the print setting screen as a list. In this process, a print apparatus 102 at the top of the list is selected. The OS print module 202 requests the OS-standard print control component 203 to obtain the settable printing information of the print apparatus 102 selected on the print setting screen.
In response to the request from the OS print module 202, the OS-standard print control component 203 obtains the settable printing information from the print apparatus 102 by using the OS-standard print protocol IPP. While obtaining the settable printing information, the OS-standard print control component 203 requests Get-Printer-Attributes from the print apparatus 102 by using the IPP protocol. In response to this request, the print apparatus 102 returns Printer-Attributes to the OS-standard print control component 203. In the case of requesting Get-Printer-Attributes, the OS-standard print control component 203 may inquire about specific settable printing information or may inquire all kinds of settable printing information that the print apparatus 102 can set. The specific settable printing information includes a supported print data format.
Thus, while Get-Printer-Attributes is requested, the OS-standard print control component 203 requests the supported print data format. The print data format is used to determine a format of the print data generated by the OS print module 202 cooperating with the application 201. The OS print module 202 compliant with IPP Everywhere uses PWG Raster Format or Portable Document Format (PDF) as a print data format. In a case where the print apparatus 102 supports multiple print data formats, the OS print module 202 generates print data in any of the print data formats that is determined as an appropriate format by the OS print module 202 itself.
The OS print module 202 displays the print setting screen in response to the printing instruction from the application 201, and once the print setting is determined, the OS print module 202 generates print data. The OS print module 202 then transmits the print data and the print setting to the print apparatus 102 by using the IPP protocol through the OS-standard print control component 203. In this process, the print setting determined on the print setting screen is transmitted to the print apparatus 102 as print setting attribute information (Job Template Attributes) by the IPP protocol.
The print apparatus 102 performs printing on a paper surface based on the print data transmitted from the OS-standard print control component 203. In this process, the print apparatus 102 forms the print data on the paper surface with an operation according to the print setting attribute information. The print setting attribute information includes a print quality, designation of two-sided printing, and so on. For example, in a case where the print setting attribute information includes the designation of two-sided printing, the print apparatus 102 executes two-sided printing. The OS print module 202 allows the user to designate the printing function available in each print apparatus 102 depending on the print apparatuses 102 connected to the print system, through the OS-standard print control component 203. That is, even in a case where a print apparatus having a different printing function or a print apparatus developed by a different vender is connected, the OS print module 202 still allows the user to designate the available printing function depending on the print apparatus connected to the print system.
The above-described control is a control for a case where the print apparatus 102 is a device supporting the OS-standard printing function. In a case where the print apparatus 102 does not support the OS-standard printing function, the OS-standard print control component 203 cannot obtain the settable printing information from the print apparatus 102. In such a case, the print conversion utility 204 is used. Hereinafter, an example of using the print conversion utility 204 is described.
The print conversion utility 204 is a utility application that interconverts the OS-standard print protocol used by the OS-standard print control component 203 and a protocol unique to the print apparatus 102 used by the print apparatus 102. The print conversion utility 204 includes a vender print module 205, which is supported by the print conversion utility 204 itself, to cause the print apparatus 102 not supporting the OS-standard print protocol to perform printing. The vender print module 205 can search for the print apparatus 102 connected to the print system through the input-output interface 116 and obtain the settable printing information by using the protocol unique to the print apparatus 102 through a vender print control component 206.
In the activation, the print conversion utility 204 requests the vender print module 205 to search for the print apparatus not supporting the OS-standard print protocol. Once receiving this request, the vender print module 205 searches for the connected print apparatus 102 by using the protocol unique to the print apparatus 102 through the vender print control component 206. The protocol used for the searching may be not only the protocol unique to the print apparatus 102 but may also be a general discovery protocol like Bonjour described above. A discovery protocol capable of searching for the print apparatus 102 not supporting the OS-standard print protocol may be used. The vender print module 205 returns a list of the print apparatuses 102 not supporting the OS-standard print protocol discovered by the searching to the print conversion utility 204.
Out of the print apparatuses 102 not supporting the OS-standard print protocol included in the returned list, the print conversion utility 204 notifies of a print apparatus 102 supported by the print conversion utility 204 itself as a print apparatus supporting the OS-standard printing function. In other words, the print conversion utility 204 makes the notification so that the OS print module 202 can discover the print apparatus 102 as the print apparatus supporting the OS-standard printing function. This method of notification is performed by using the Bonjour protocol, for example. To be more specific, the print apparatus 102 supported by the print conversion utility 204 is notified as Service Instance Name of “_ipp._tcp,_print” as DNS Service Discovery.
The request of searching for the print apparatus not supporting the OS-standard print protocol from the print conversion utility 204 to the vender print module 205 may be executed not only in the activation. For example, the searching request may be made by the print conversion utility 204 at specific intervals. Additionally, the print conversion utility 204 may notify the vender print module 205 of information on the print apparatus 102 supported by itself. The vender print module 205 then may return only the print apparatus 102 supported by the print conversion utility 204 as a search result.
In a case where the print conversion utility 204 receives from the OS print module 202 a request of obtaining the settable printing information of the print apparatus that is notified as the print apparatus supporting the OS-standard printing function by the print conversion utility 204, the print conversion utility 204 performs the following operations. If there is a request of Get-Printer-Attributes of the print apparatus designated by the OS-standard print control component 203, the print conversion utility 204 executes processing of obtaining the settable printing information of the designated print apparatus. Specifically, the print conversion utility 204 requests the settable printing information of the designated print apparatus not supporting the OS-standard print protocol from the vender print module 205. The vender print module 205 obtains settable printing information that the print apparatus supports by using the protocol unique to the print apparatus 102 through the vender print control component 206 and returns the result to the print conversion utility 204.
In a case where, for example, the vender print module 205 has the settable printing information of the print apparatus 102 in a static data format, the settable printing information may be returned directly to the print conversion utility 204 without using the vender print control component 206. The print conversion utility 204 returns the settable printing information of the print apparatus obtained from the vender print module 205, the print apparatus not supporting the OS-standard print protocol and designated by the OS print module 202, to the OS print module 202.
The print conversion utility 204 also has a function of converting a print data format generated by the OS print module 202 to a print data format supported by the vender print module 205. With the print conversion utility 204 answering in behalf of the print apparatus not supporting the OS-standard print protocol or performing the print data format conversion, it is possible to allow the print apparatus not supporting the OS-standard print protocol to perform printing using the OS-standard printing function.
If the capability of the print apparatus not supporting the OS-standard print protocol and the print data and the print setting transmitted by the OS print module 202 according to the OS-standard print protocol do not match each other, there may be a case that proper processing is not executed. Hereinafter, an example where the print conversion utility 204 executes proper processing depending on the capability of the print apparatus not supporting the OS-standard print protocol and the print data and the print setting transmitted by the OS print module 202 according to the OS-standard print protocol is described.
Hereinafter, first, a print setting screen depending on the capability of the print apparatus is described. Specifically, a configuration of the print setting screen for a case where the print apparatus not supporting the OS-standard printing function is caused to perform printing using the OS-standard printing function is described. Hereinafter, the description is given with the assumption that a print apparatus not supporting the OS-standard printing function, “Company C Printer 1”, supported by the print conversion utility 204 is connected to the print system.
Additionally, it is assumed that the print apparatus 102 has a capability of setting the following printing functions. (1) The print apparatus 102 has a function of accepting a designation of the number of copies and copying the designated number of copies of print data in the print apparatus. (2) The print apparatus 102 has a collation printing function and can perform a collation output in a unit of the designated number of copies but cannot perform an output of the designated number of copies in the order of pages if collation printing is not designated. (3) The print apparatus 102 does not have a two-sided printing function; therefore, the print apparatus 102 cannot accept designation of the two-sided printing function. (4) The print apparatus 102 supports sheet sizes of A4 and letter-size and has a function of receiving print data corresponding to the sheet sizes and performing printing for the sheet sizes. (5) The print apparatus 102 supports sheet types of plain paper and a photo sheet and has a function of performing printing on a paper surface of a designated type of sheet. (6) The print apparatus 102 includes only a main tray as a paper feed port.
First, the print conversion utility 204 makes notification so that the print apparatus not supporting the OS-standard printing function, “Company C Printer 1”, can be discovered by the OS print module 202 as the print apparatus supporting the OS-standard printing function. The method of notification is made by the Bonjour protocol as described above. In a case where obtaining of settable printing information of the print apparatus not supporting the OS-standard printing function, “Company C Printer 1”, is requested by the OS print module 202, the print conversion utility 204 answers on behalf of the print apparatus. The method of answering on behalf of the print apparatus includes to answer the settable printing information of the print apparatus not supporting the OS-standard printing function, “Company C Printer 1”, by using the IPP protocol, as described above. Additionally, the following descriptions are given with the assumption that, in a case where the OS print module 202 inquiries about a print data format as the settable printing information, the print conversion utility 204 answers PWG Raster Format and PDF.
Once receiving the printing request from the user, the application 201 issues the printing instruction to the OS. Once receiving the printing instruction, the OS print module 202 provides the application 201 with the print setting screen configured to display the list of the available print apparatus supporting the OS-standard printing function and the print setting that can be set for the print apparatus and the set values thereof.
The OS print module 202 displays the print apparatus obtained from the OS-standard print control component 203 in a printer list 301 in a print setting dialogue 300 such that the print apparatus is being selected. Next, the OS print module 202 requests the settable printing information from the print apparatus selected in the printer list 301 by using the IPP protocol. In this case, the print conversion utility 204 answers the settable printing information of “Company C Printer 1” on behalf of the selected print apparatus.
(a) The OS print module 202 requests an attribute of how many number of copies of print data can be copied at most in the print apparatus. The attribute information corresponds to “copies-supported”. (b) The OS print module 202 requests a print data format that the print apparatus supports. The attribute information corresponds to “document-format-supported”. (c) The OS print module 202 requests a paper feed port that the print apparatus supports. The attribute information corresponds to “media-source-supported”. (d) The OS print module 202 requests an aggregate of pieces of sheet information that the print apparatus supports. The aggregate of pieces of sheet information includes information such as a name of sheet size, a physical sheet size, and a blank size, and the attribute information corresponds to “media-col-database”. (e) The OS print module 202 requests a sheet size that the print apparatus supports. The attribute information corresponds to “media-supported”. (f) The OS print module 202 requests a default sheet size name of the print apparatus. The attribute information corresponds to “media-default”. (g) The OS print module 202 requests a sheet type that the print apparatus supports. The attribute information corresponds to “media-type-supported”. (h) The OS print module 202 requests a two-sided printing function that the print apparatus supports. The attribute information corresponds to “sides-supported”. (i) The OS print module 202 requests a default two-sided printing function of the print apparatus. The attribute information corresponds to “sides-default”. (j) The OS print module 202 requests a collation printing function that the print apparatus supports. The attribute information corresponds to “multiple-document-handling-supported”.
In response to the requests of those attributes from the OS print module 202, the print conversion utility 204 answers the following as the attributes of the settable printing information of “Company C Printer 1” on behalf of the print apparatus.
(A) The print conversion utility 204 answers “1-255”, which indicates that the print apparatus can print and copy 255 copies at most, to “copies-supported”. (B) The print conversion utility 204 answers a print data format that the print apparatus supports to “document-format-supported”. In this case, the print conversion utility 204 answers “application/pdf,image/pwg-raster”, which indicates that the print apparatus supports print data formats of PDF and PWG-Raster Format. In this case, “Company C Printer 1” is a print apparatus not supporting the OS-standard printing function and does not support those print data formats; however, the print conversion utility 204 converts the formats to supported print data formats through the vender print module. (C) The print conversion utility 204 answers “main”, which indicates that the print apparatus supports the main tray as a supported paper feed port, to “media-source-supported”.
(D) The print conversion utility 204 answers the sheet size that the print apparatus supports to “media-col-database” as described below. The name of sheet size of A4-size that the print apparatus supports is answered as “iso_a4_210×297mm”. The sheet of A4-size in a physical size is a width of 210 mm and a length of 297 mm. The physical size is expressed in terms of one hundredth mm and answered as “x-dimension=21000 y-dimension=29700”. The print apparatus needs to provide blanks of 4 mm in four sides in the printing. The blank size is also expressed in terms of one hundredth mm and answered as “media-bottom-margin=400, media-left-margin=400, media-right-margin=400, and media-top-margin=400”. This blank size is common between A4-size and letter-size, and the same answer is made for both A4-size and letter-size. The sheet size name of letter-size that the print apparatus supports is answered as “na_letter_8.5×11 in”. The sheet of letter-size in the physical size is a width of 215.9 mm and a length of 279.4 mm. The physical size is expressed in terms of one hundredth and answered as “x-dimension=21590 y-dimension=27940”. (E) The print conversion utility 204 answers “iso_a4_210×297 mm” and “na_letter_8.5×11 in” as the sheet sizes that the print apparatus supports to “media-supported”.
(F) The print conversion utility 204 answers “iso_a4_210×297 mm”, which indicates that the default sheet size of the print apparatus is A4-size, to “media-default”. (G) The print conversion utility 204 answers “stationery,photo”, which indicates that the sheet types that the print apparatus supports are plain paper and photo paper, to “media-type-supported”. (H) The print conversion utility 204 answers “one-sided”, which indicates that the print apparatus does not support two-sided printing and supports only one-sided printing, to “sides-supported”. (I) The print conversion utility 204 answers “one-sided”, which indicates that the print apparatus does not support the default two-sided printing function of print apparatus, to “sides-default”.
(J) The print conversion utility 204 answers to indicate that the collation printing that the print apparatus supports is only the collation output in a unit of copies. In this process, “separate-documents-collated-copies” is answered to “multiple-document-handling-supported”.
According to the thus-obtained attribute information, the OS print module 202 configures settable items for printing to be displayed in the print setting dialogue 300. A number-of-copies designation text box 302 is a control for performing printing of the designated number of copies that is configured according to the obtained “copies” attribute. A print page designation radio button 303 is a control related to designation of a page of print data generated by the cooperating OS print module 202 and application 201. If “all” is selected, print data of all the pages of the contents created by the application is generated. On the other hand, if a page range is designated, print data of the page range set in “start” and “end” of a page designation range text box 304 is generated.
A collation printing designation check box 305 is configured according to the obtained “multiple-document-handling-supported” attribute. The operation according to the collation printing designation is described later.
A sheet size designation list 306 is configured according to the obtained “media-supported” attribute. In this case, the sheet sizes of A4-size and letter-size are listed in the sheet size designation list 306, and the obtained “media-default” is being selected. In this case, A4-size is being selected in the sheet size designation list 306. A sheet type designation list 307 is configured according to the obtained “media-type-supported”. Here, plain paper and photo paper are listed. In this case, plain paper corresponding to “stationery” that is returned first to the “media-type-supported” attribute is being selected in the sheet type designation list 307.
In this embodiment, since the print apparatus 102 does not support the two-sided printing function, the print setting dialogue 300 does not display a control of two-sided printing. A cancel button 308 is a control of canceling the printing instruction, and once the user presses the cancel button 308, the OS print module 202 hides the print setting dialogue 300, and the process returns to the processing of the application 201. A print button 309 is a control of instructing the print apparatus to perform printing with the print setting designated by the controls in the print setting dialogue 300. Once the user presses the print button 309, the OS print module 202 cooperates with the application 201 to generate print data and print setting based on the determined print setting, and printing is performed in the print apparatus through the print conversion utility 204.
A method of allowing the print apparatus not supporting the OS-standard printing function to print contents including multiple pages using the OS-standard printing function is described.
The OS print module 202 generates print data according to the “document-format-supported” attribute answered by the print conversion utility 204 on behalf of the print apparatus. In a case where there are multiple supported print data formats like this embodiment, the OS print module 202 may generate the print data in a print data format that is determined as an appropriate format by the OS print module 202 itself depending on the designation by the application 201 or the designation by the OS 210. For example, in a case where printing of image data such as a photo can be recognized in advance, the OS print module 202 may generate the print data in PWG Raster Format, which is a raster data format. On the other hand, in a case where printing of data such as texts or a drawing can be recognized in advance, the OS print module 202 may generate the print data in a PDF format, which is a vector data format.
If the print conversion utility 204 according to this embodiment is not used, there may be a case where improper processing for the printing of the contents including multiple pages may be executed by the print apparatus 102 not supporting the OS-standard printing function. Specifically, processing that causes an increase in a processing load or occupation of a storage region may be executed. Additionally, collation printing in a form desired by the user may not performed.
First, processing in a case of using a print conversion utility not according to this embodiment is described as a comparative example. With the print conversion utility of the comparative example, processing of the vender print module 205 that generates data to cause the print apparatus 102 to perform printing using the print data and the print setting received from the OS print module 202 is executed. That is, unlike the print conversion utility 204 of this embodiment described later, generation processing according to the printing capability of the print apparatus 102 is not executed. For example, in a case where
Next, a comparative example where collation printing in a form desired by the user is not performed is described. First, collation printing is described simply. Collation printing (also referred to as collation output) is printing (output) performed in a unit of copies. For example, here is assumed that two copies of contents including a first page and a second page are printed. In this case, if collation printing is performed, the print apparatus performs printing in the order of a first page of the first copy, a second page of the first copy, a first page of the second copy, and a second page of the second copy. That is, printing is performed in a unit of copies. On the other hand, in a case where collation printing is not performed, printing of multiple number of copies is performed in the order of pages. For example, in the above-described example, printing is performed in the order of the first page of the first copy, the first page of the second copy, the second page of the first copy, and the second page of the second copy.
In a case of using the OS-standard printing function, the OS print module 202 during the printing of the designated number of copies may generate print data while assuming that the print apparatus can achieve both the collation printing in a unit of the designated number of copies and the printing of multiple number of copies designated in the order of pages. On the other hand, some of the print apparatuses can execute collation printing but cannot execute printing of multiple number of copies designated in the order of pages. As described above, the print apparatus of this embodiment has the collation printing function and can perform the collation output in a unit of the designated number of copies. However, if collation printing is not designated, the print apparatus cannot perform an output by printing of multiple number of copies designated in the order of pages. Thus, the print apparatus that cannot copy print data of multiple number of copies in the order of pages in the print apparatus is incapable of properly processing the setting of the print apparatus supporting the collation output in the vender print module and is incapable of obtaining a desired output result. That is, an output by the collation printing may be performed although print data in which collation printing is not designated (collation printing OFF) is transmitted by the OS print module 202. The OS print module 202 obtains “separate-documents-collated-copies” from the print conversion utility as the settable printing information. Accordingly, the collation printing designation check box 305 is displayed in the print setting dialogue 300 of
To deal with this, the print conversion utility 204 of this embodiment executes processing of inhibiting the improper processing in a case of printing the contents including multiple pages.
In S601, the print conversion utility 204 obtains print setting and print data from the OS print module 202.
The print conversion utility 204 obtains the following print settings during the Create-Job operation. (J1) The print conversion utility 204 obtains sheet information for the printing by the print apparatus from the media-col attribute. In this case, the print conversion utility 204 obtains the sheet information indicating use of A4-size as the sheet size, the main tray as the paper feed port, and plain paper as the sheet type, as described above. (J2) The print conversion utility 204 obtains setting of one-side printing from the sides attribute. (J3) The print conversion utility 204 obtains setting of performing collation printing from the multiple-document-handling attribute. (J4) The print conversion utility 204 obtains setting of copying two copies of print data in the print apparatus from the copies attribute.
The print conversion utility 204 obtains the print data during the Send-Document operation. During the obtainment of the print data, the print conversion utility 204 can grasp the format of the print data from document-format as an operation attribute. In this case, the print conversion utility 204 grasps that the format of the print data is PDF.
In S602, the print conversion utility 204 makes a determination on the format of the print data obtained in S601. If the format of the print data is a vector data format such as PDF, the process proceeds to S603 for the processing for vector data, and if the format of the print data is a raster data format such as PWG-Raster, the process proceeds to S604. In the case of the example in
Next, in S802, the print conversion utility 204 determines whether the print apparatus supports the function of copying the designated number of copies. If the print apparatus supports the function of copying the designated number of copies, the process proceeds to S803, and if the print apparatus does not support the function, the process proceeds to S805. In this example, the process proceeds to S803 since the print apparatus has the function of copying the designated number of copies in the print apparatus.
In S803, the print conversion utility 204 determines whether the collation setting of the print job obtained from the OS print module 202 is a function that the print apparatus can process. If the collation setting of the print job obtained from the OS print module 202 is a function that the print apparatus can process, the process proceeds to S804, and if it is not, the process proceeds to S805. In this example, the process proceeds to S804 since the collation setting of the print job is setting of performing collation printing, and the print apparatus has the function of collation printing in a unit of copies.
In S804, the print conversion utility 204 asks the vender print module 205 to execute the print processing without reconfiguring the print setting and the print data of the print job obtained from the OS print module 202. The meaning of this processing is that processing of the the print setting and the print data from the OS print module 202 by the vender print module 205 allows the print apparatus 102 to execute the processing with proper setting. In other words, it means that the print system can perform printing while reducing a communication load during collation printing.
In S805, the print conversion utility 204 reconfigures the print data according to the collation setting of the obtained print job and the setting of the designated number of copies to be printed, changes the setting of the number of copies to be printed to “1”, and asks the vender print module 205 to execute the print processing.
Here is described the example where the process proceeds to S805 and the processing is executed regardless of the number of copies to be printed and the number of pages of the print data. However, the phenomenon where the printing of multiple number of copies in the order of pages is not made if the setting of collation printing of the print job does not correspond to the collation printing function of the print apparatus occurs in a case where the number of copies to be printed is two or greater and the number of pages is two pages or greater. To deal with this, determination on whether the number of copies to be printed and the number of pages are both plural may be made, and the process may proceed to S805 if both the number of copies to be printed and the number of pages are plural.
Next, an example where the OS print module 202 in this embodiment outputs print data in a print data format of a raster data format to the print conversion utility 204 is described.
The print conversion utility 204 obtains the expanded print data including four pages in total from the OS print module 202. The print conversion utility 204 can obtain the number of print sides of a copy of the print data from job-impressions as an operation attribute. In the example of
In S1302, the print conversion utility 204 determines whether the print apparatus 102 supports the function of copying the designated number of copies. If the print apparatus supports the function of copying the designated number of copies, the process proceeds to S1303, and if the print apparatus does not support the function, the process proceeds to S1306. In this example, the process proceeds to S1303 since the print apparatus 102 has the function of copying the designated number of copies in the print apparatus.
In S1303, the print conversion utility 204 determines whether the collation setting of the print job obtained from the OS print module 202 is a function that the print apparatus 102 can process. If the print job obtained from the OS print module 202 is a function that the print apparatus 102 can process, the process proceeds to S1304, and if it is not, the process proceeds to S1306. In this example, the process proceeds to S1304 since the collation setting of the print job is setting of performing collation printing, and the print apparatus has the function of collation printing in a unit of copies.
In S1304, the print conversion utility 204 determines the number of copies to be printed, and if the number of copies to be printed is two copies or greater, the process proceeds to S1305, and if it is one copy, the process proceeds to S1306. In this example, the process proceeds to S1305 since the total number of pages of the print data is four pages, and the number of copies to be printed is determined as “2” as the number of print sides of each copy is “2”.
In S1305, the print conversion utility 204 reconfigures print data of a copy by using the collation setting and the number of print sides of the print job obtained from the OS print module 202. In this case, the collation setting of the print job is collation printing, and the number of print sides of each copy is “2”. The print apparatus 102 supports the function of copying the designated number of copies. Accordingly, even without transmitting the expanded print data of all the total number of pages to the print apparatus 102, it is possible to obtain a similar print result with the print apparatus 102 performing collation printing of multiple number of copies by using the print data of one copy. Hence, in S1305, the print conversion utility 204 reconfigures the print data by using the data 1201 of the first page and the data 1202 of the second page of the print data obtained from the OS print module 202 illustrated in
Another example is described. Here is described processing for a case where the print conversion utility 204 obtains raster data from the OS print module 202 as the print data while the collation printing designation check box 305 is not checked in the print setting dialogue 300.
As described above, the print apparatus 102 of this example has the collation printing function and can perform the collation output in a unit of the designated number of copies. However, in a case where collation printing is not designated, the print apparatus 102 cannot perform the output of the designated number of copies in the order of pages. Hence, in this example, the print conversion utility 204 determines that the setting of collation printing of the print job does not correspond to the collation printing function of the print apparatus in S1303 of the processing flowchart for raster data in
In S1306, the print conversion utility 204 asks the vender print module 205 to perform the print processing without reconfiguring the print setting and the print data of the obtained print job. In this way, it is possible to obtain an output result of the printing of the designated number of copies in the order of pages by the print apparatus that does not have the function of printing the designated number of copies in the order of pages.
As described above, according to this embodiment, it is possible to allow the print apparatus not supporting the OS-standard printing function to execute proper print processing using the OS-standard printing function. In other words, it is possible to execute the print processing while inhibiting the processing that causes an increase in a processing load and occupation of a storage region. Additionally, it is possible to perform collation printing in a form that the user desires.
The attribute information obtained by using the OS-standard print protocol is used to obtain the print setting and the print data of the print job from the OS-standard print control component 203 in this embodiment; however, the information may be obtained from meta-data and the like included in the print data. Additionally, in this embodiment, the print conversion utility 204 switches the processing for the case of vector data and the processing for the case of raster data depending on the file format of the print data obtained from the OS print module 202 in S602. In a case where the OS print module 202 outputs one type of print data format, processing of a default data format may be executed without making the determination in S602.
In this embodiment, a method of allowing a print apparatus not supporting the OS-standard printing function to perform two-sided printing of contents including multiple pages using the OS-standard printing function is described. Portions with no descriptions hereinafter are similar to that in the first embodiment.
In this embodiment, descriptions are given with the assumption that a print apparatus not supporting the OS-standard printing function that is supported by the print conversion utility 204, “Company C Printer 2”, is connected to the print system as the print apparatus 102. Additionally, it is assumed that the print apparatus 102 not supporting the OS-standard printing function has a capability of setting the following functions. (1) The print apparatus has a function of accepting a designation of the number of copies and copying the designated number of copies of print data in the print apparatus. (2) The print apparatus has a collation printing function and can perform collation printing in a unit of the designated number of copies but cannot perform an output of the designated number of copies in the order of pages if collation printing is not designated. (3) The print apparatus has a two-sided printing function and can perform a two-sided printing output of short-edge binding by accepting designation of the two-sided printing function. (4) The print apparatus supports sheet sizes of A4 and letter-size and has a function of receiving print data corresponding to the sheet sizes and performing printing for the sheet sizes. (5) The print apparatus supports sheet types of plain paper and a photo sheet and has a function of performing printing on a paper surface of a designated type of sheet. (6) The print apparatus includes only a main tray as a paper feed port.
First, the print conversion utility 204 makes notification so that the print apparatus not supporting the OS-standard printing function, “Company C Printer 2”, can be discovered by the OS print module 202 as the print apparatus supporting the OS-standard printing function. The method of notification is made by the Bonjour protocol, as described above. In a case where obtaining of settable printing information of the print apparatus not supporting the OS-standard printing function, “Company C Printer 2”, is requested by the OS print module 202, the print conversion utility 204 answers on behalf of the print apparatus. The method of answering on behalf of the print apparatus includes to answer the settable printing information of the print apparatus not supporting the OS-standard printing function, “Company C Printer 2”, by using the IPP protocol, as described above. Additionally, the following descriptions are given with the assumption that, in a case where the OS print module 202 inquiries about a print data format as the settable printing information, the print conversion utility 204 answers PWG Raster Format and PDF.
Once receiving the printing request from the user, the application 201 issues the printing instruction to the OS. Once receiving the printing instruction, the OS print module 202 provides the application 201 with the print setting screen configured to display the list of the available print apparatus supporting the OS-standard printing function and the print setting that can be set for the print apparatus and the set values thereof.
In a case where the obtained attribute information “sides-supported” corresponds to two-sided printing, the OS print module 202 displays a two-sided printing control 1703. While a check box of the two-sided printing control 1703 is checked, the user can select a radio button for selecting long-edge binding or short-edge binding. Although in a case where the print apparatus supports two-sided printing but has only either function of long-edge binding and short-edge binding, the OS print module 202 may provide a control that allows selecting of both the functions of long-edge binding and short-edge binding.
It is assumed that the contents of this embodiment are the same as the contents described in the first embodiment. The contents of this embodiment are the contents created by the application 201 and includes the two pages in total, which are the contents 501 on the first page and the contents 502 on the second page, as illustrated in
In this embodiment, PDF in a vector data format illustrated in
The print conversion utility 204 in this embodiment also executes the print processing through the processing indicated in
In S2105, the print conversion utility 204 determines whether the setting of two-sided printing of the print job obtained from the OS print module 202 supports the capability of two-sided printing of the print apparatus. In this case, the process proceeds to S2106 since long-edge binding corresponding to two-sided-long-edge is set to the setting of two-sided printing of the print job but the print apparatus does not support an output of long-edge binding.
In S2106, the print conversion utility 204 reconfigures the print data based on the setting of double-side printing of the print job obtained from the OS print module 202. In this case, the following descriptions are given with the assumption that the print apparatus of this embodiment that supports an output of short-edge binding in two-sided printing can obtain the same output result as an output of long-edge binding in a case where the data on an even-numbered page is rotated 180 degrees in the two-sided printing (in output of short-edge binding).
Next, in S2107, the print conversion utility 204 asks the vender print module 205 to execute the print processing to perform printing in the print apparatus 102. This makes it possible to perform printing with proper print setting in the print apparatus having either the function of an output of short-edge binding or an output of long-edge binding for setting of two-sided printing, even in a case where setting of two-sided printing that the print apparatus does not support is set for printing by the print apparatus.
Next, in this embodiment, an example of a case where the OS print module 202 outputs print data in a raster data format as print data once the print button 1710 in the print setting dialogue 1700 illustrated in
Thereafter, the print conversion utility 204 executes the processing for raster data indicated in
In this embodiment, here is described, as with the first embodiment, an example where the print apparatus 102 has the collation printing function and can perform the collation output in a unit of the designated number of copies but cannot perform an output of the designated number of copies in the order of pages if the collation printing is not designated. However, the configuration is not limited to this example. The print apparatus may have the two-sided printing function but no collation printing function. Otherwise, the print apparatus may be an apparatus that has the collation printing function and can perform both the collation output in a unit of the designated number of copies and output of the designated number of copies in the order of pages. In this case, the processing in
In this embodiment, an example of using a cloud print service provided on the Internet and printing is performed with proper print setting by a print apparatus not supporting the cloud print service is described.
The print conversion service 2303 is a service to convert print data that the cloud print service 2302 provides into a print data format that the print apparatus 102 not supporting the cloud print service 2302 can print. This conversion service is operated in an environment where a connection with the cloud print service 2302 on the Internet can be made through the Internet. The conversion service may be an application that is operated on the client terminal 2301 such as a PC or a smartphone that is connected to the Internet. The print conversion service 2303 communicates with the cloud print service 2302 by using a protocol that the cloud print service 2302 supports. The print conversion service 2303 also communicates with the print apparatus 102 by using a protocol that the print apparatus 102 supports and interconverts the protocol. A widely known examples of the cloud print service 2302 are Google Cloud Print (registered trademark) of Google (registered trademark) and print services provided by print apparatus venders.
Information on the print apparatus 102 that performs printing is registered in the cloud print service 2302 in advance. In this example, the information on the print apparatus 102 not supporting the cloud print service 2302 is registered in the cloud print service 2302 through the print conversion service 2303. The information on the print apparatus 102 includes the capability of the print apparatus. In this case, descriptions of a user who instructs printing by using the client terminal 2301 and a method of authentication between the cloud print service 2302 and the print conversion service 2303 are omitted.
As described above, the cloud print service 2302 is a service corresponding to the OS print module described in the first embodiment, and the print conversion service 2303 is a service corresponding to the print conversion utility 204.
The user makes an instruction by using the client terminal 2301, and the client terminal 2301 or a not-illustrated service on the Internet providing print contents provides the cloud print service 2302 with print contents. It is assumed that the cloud print service 2302 provides a function that allows the user to select print setting based on the information on the capability of the print apparatus 102 performing printing that is obtained from the print conversion service 2303. For example, if the printing apparatus is the one having the same capability as that of the print apparatus 102 in the above-described first embodiment, the user can select the collation printing function.
Once receiving print setting from the user, the cloud print service 2302 transmits the print data and the print setting to the print conversion service 2303. Descriptions of a communication protocol of the print setting and the print data between the cloud print service 2302 and the print conversion service 2303 are omitted herein. Note that, the IPP described in the first embodiment may be used. Thereafter, the print conversion service 2303 executes print processing indicated in
In this case, in the processing for vector data in S2403, printing is performed with proper print setting by the print apparatus 102 through a not-illustrated vender print module in the print conversion service 2303 by using the processing for vector data in
As described above, according to this embodiment, it is possible to allow the print apparatus 102 not supporting the cloud print service 2302 to perform printing with proper print setting using the cloud print service 2302. Additionally, as described in the second embodiment, also in a case of two-sided printing, it is possible to perform printing with proper print setting similarly in the print system of this embodiment.
